The fiber optic sensor system uses two fiber ferrule sensors that are bonded on either side of a cantilever beam to measure the flow rate by monitoring the air-gap changes caused by the bending of the cantilever beam. The accurate monitoring of flow velocity is crucial in applications such as blood microcirculation and microfluidic systems. Cross sensitivity of the temperature and pressure dependence of the sensor can be. The real-time monitoring of the flow environment parameters, such as flow velocity and direction, helps to accurately analyze the effect of water scour and provide technical support for the maintenance of pier and abutment foundations in water.
